I'm from Southwestern Ontario. I was wondering how many Deciduous Conifers there are. I know there's a Tamarack which is a Tall growing spruce like tree with green needles in the summer. In the winter the needles change to a yellow color and then fall off in the winter time.

Does anyone know of any other Deciduous Conifer in the Southern part of Ontario?

Thats it?? wow, i need to collect a cutting from a deciduous conifer for next week. as it looks like a tamarack is the best option for me right now. The only problem with this is that all the branches are very brital. (larix laricina K.Koch)

Does anyone know of any other plant that would be better used to take a clipping from and press it on a piece of paper?

I'd think Larix laricina is the only one that will be at all common in Ontario. The next commonest will probably be Larix decidua, then Metasequoia glyptostroboides and Taxodium distichum, these getting distinctly hard to find (likely only in places where you'll need to get special permission to pick twigs).

Larch twigs are not very brittle unless they've been dead a year or two (after that, they do get very brittle). Maybe you picked a dead twig from low down on a tree's crown, when all the live growth is higher up?

lol Did you fall out of one? So Ginkgo is a gymnosperm. Why do people always say this is the only conifer that does not look like one (and I mean "lecturerers"). Apparently extracts from the Gingko help symtoms of insufficient blood circulation to the brain, including memory loss and confusion. I think I may need some.

The Dawn Redwood is deciduous and recently introduced into the U.S.
Botanical name: Metasequoia glyptostroboides

I understand this was once thought extinct, but it is supposedly native to the Sichuan–Hubei region of China and was rediscovered in 1944. It will grow to 200'. It has beautiful bark, but all the shedding every fall is a mess.
